First cut at restructuring how variable matching works in the pattern

language. The goal is to remove the strict behavior of using only one
element of context after a variable.
variable form at parse time: we unravel that first.

* parser.y (grammar): Simplifying the phrase structure
rule for the var element. All the variants that have
a trailing elem are removed. The abstract syntax
changes; the modifier moves to the third position in the
list.

* match.c (h_var): Matching change: the element which follows
a variable is now pulled from the specline rather than the variable
syntax, which is how it should have been done in the first place. The
modifiers are pulled from a different spot in the variable syntax.
